In electric vehicles (EVs), Li-ion battery has been applied as the main power source. To give enough power and energy to the system, single Li-ion battery cells will be connected in series and parallel to make a battery pack. Thus, cell equalization for battery pack has been an important topic in battery management system (BMS). Recently, researches have proposed different topologies and control strategies...
A hybrid distributed generation system (HDGS) using a multi-input multi-output positive buck-boost converter (MIMO-PBBC) is proposed for the supply-side of the grid-connected photovoltaic (PV) generation power plant, where three PV clusters, one battery bank, and one supercapacitor module are hybridized and regulated by a centralized three-phase dc-ac inverter with their corresponding control systems...
In this paper, an adaptive observer is applied to estimate the internal temperature of a lithium-ion cell in a battery pack. The cell's internal temperature is an important factor for its degradation, but it cannot be measured directly. Based on the measured surface temperature and a lumped thermal model for the battery pack, an adaptive observer is designed to estimate the internal temperature and...
An accurate battery State of Charge (SOC) estimation is very important for electric vehicles. In this paper, a method is proposed to estimate the SOC of the lithium-ion batteries using radial basis function (RBF) networks and the adaptive unscented Kalman filter (AUKF). The RBF networks are to model the battery-discharging process, then the AUKF is applied to estimate the SOC of the battery. Simulation...
Proton exchange membrane fuel cell (PEMFC) has a time-delay feature on its electrical characteristic. So other energy sources with relatively higher response rate and better dynamic performance is necessary for assisting and sharing responsibility with PEMFC in hybrid power supply system. Multi-input DC/DC converter, which has higher efficiency, less component count, lower cost and simpler control...
